Description

Prefabricated modular tower
Technical field
Point out as title, this manual relates to a kind of prefabricated modular tower, it is as the bracing or strutting arrangement of wind-driven generator and miscellaneous equipment, it is characterized in that the prefabricated elements that it uses preferably the minimizing thickness of being made by steel concrete, these prefabricated elements utilize the internal construction of level and vertical stiffening rib to strengthen; Described element by means of the flexible metal cable flatly and vertically tensioning.
Background technology
Have a variety ofly by wind-driven generator at present, they are also referred to as wind-driven generator.These generators comprise the vaned turbine of connection, and this turbine support is on tower.
Great majority generator support tower more commonly used is a metal, and or have cancelled structure, perhaps have the shape of columned or conical hollow.The tower of these types has a series of problem, in these problems, we will should be mentioned that need be by antirust processing or spray paint carry out frequent maintenance, since scrapping of producing of fatigue of materials (the constantly tension and compression repeatedly that wind-force causes) because they have to bear cause be less than vicennial short life and high manufacturing, transportation and installation cost usually.
Another problem is that from the angle of technology and economy, they can only be used for the height between 25 to 40m.For the height that surpasses 50m, metal tower begins to become and can not implement, because the expensive height that limits wind-driven generator to a great extent of rigidity that they meet with stresses and material therefor.
The construction trend of wind-driven generator is the power that increases them at present, and makes more location, highland of turbine and blade.Turbine also is equipped with much bigger blade, avoiding the screen effect in mountain region, and utilize the more stable higher air layer of air-flow, thereby its amount of having an effect is bigger as far as possible.
This means and to find replacement scheme that tower builds to cater to above 50m and in fact near 90 or the height of 100m.Required rigidity means that to build these towers with metal construction no longer feasible, therefore attempts building these towers with harder, durable and economic many steel concrete.
As building and skyscraper, some towers use the framework built on-site of lattice or similar structures form, but it has the shortcoming that technology is slow, cost is high, especially because used cost of labor.The example of this building technology is illustrated in patent JP 200100658 " very high tower (Very talltower) " or patent DE 19936603 and " for example is used for the hollow mast in wind field or the Structural Engineering method of concrete structure such as tower; its work of using when being included in inner space mounting structure is with guide frame (Structural engineering method for hollow mast or concrete structureas a tower; for example; for a wind farm, comprising a guide structure forwork used during the construction installed in the inside space) ".
The someone attempts finding out other solution.For example patent WO 2004007955 " production method (Method for the production of a cement segmentfor a wind farm tower) that is used for the cement section of wind field tower " proposes a kind of structural system, the building site is made and is transported in this structural system use in precast concrete factory, complete stackable conical section, problem is, because the restriction of relevant law and practicality, if with the words of conventional road transport method transportation, these sections must be very short, this means that will build tower must use very a large amount of stacked segments, except that the lasting use cost of the crane that is used to install and assemble, high transport cost and cost of labor have also been produced.Another shortcoming of the method is, build the taper tower, and every section is of different sizes, this means must have with tower in the as many mould of section, this has increased the complexity of production technology.In addition, realize necessary rigidity and globality, every section wall must be quite thick, and this has increased their cost and the weight that will transport again.
In the effort aspect reducing part dimension to be transported, described in novel 200402304 " modified modular tower structures (Improved modular towerstructure for wind turbines and other applications) that are used for wind turbine and other equipment " of practicality and patent WO 03/069099 " wind turbine (Wind Turbine) ", attempt each taper mast section is divided into the part of separation, but these two patent documents all have following shortcoming, promptly, used very thick solid wall, and the interior outside of solid wall all is smooth with implementation structure rigidity and corrosion, this has improved the price of part significantly, also mean and build the more part of tower needs, thereby except the great number fabricating cost of required a large amount of mfg. moulding dies and contained high construction weight generation, also produced the transport cost and the assembling expense of great number.
In addition, the tower known to the utility model 200402504 " perfect structure (Perfected structure of a modular tower for win turbines andother applications) that is used for the modular tower of wind turbine and miscellaneous equipment " for example, the something in common of itself and other tower is, they have used the part that separates to form section, with implementation structure hardness and corrosion, used all smooth, the quite thick solid wall in the interior outside.The weight of supposing these parts increases significantly, has then produced identical problem as form tower with a large amount of parts, promptly transports and assemble both expense great numbers.In addition, in order to strengthen the structure of tower, this embodiment has adopted the outside pretensioning system that comprises vertical tensioned cables, the problem of vertical tensioned cables is the ground that must be attached to tower, thereby ground must be equipped with suitable anchoring device, another problem is that cable only is attached to wall in the through hole of the flange of described wall, this means with wall and have only part to contact, thereby booster action quite a little less than.In addition, most of cables are stayed the outside of tower inboard, wall, and are exposed in the air, except that the stress of cable and have a strong impact on they application life atmospheric loss and corrode the deterioration problem that causes, also influence visual effect.
Summary of the invention
Theme of the present invention is a prefabricated modular tower, and described tower is designed for to solve builds the problem that the subject under discussion that is used for support tower wind-driven generator and miscellaneous equipment, very high exists at present.Prefabricated modular tower uses the prefabricated elements that reduces thickness, and described element is by the level and the vertically internal construction reinforcement of stiffening rib of preferably making with steel concrete; By means of the flatly and vertical described element of tensioning of flexible metal cable.
Tower is divided into a few tapering part, and then, each tapering part by preferably make with steel concrete, a spot of identical precast module type component side forms to being coupled.In the example of preferred implementation, tower is divided into three tapering parts, and each tapering part has and is about 30 to 35m height, makes the overall height of tower be about 100m.In the example of this preferred implementation, lower part is formed by five that are arranged side by side each other identical Prefabricated block elements; Mid portion by other five also be that the identical precast module type element that is arranged side by side forms, but its diameter is significantly less than the diameter of above-mentioned Prefabricated block element; Upper part is only formed by three precast module type elements, and they are mutually the same but be different from aforesaid Prefabricated block element.Thereby illustrating, the example of this preferred implementation only use only 13 Prefabricated block elements of three kinds dissimilar---only needing three kinds of mfg. moulding dies---how to make the high tower of 100m.
The shape of each Prefabricated block element makes it form the tapering part of tower just when placed adjacent.The outer wall of Prefabricated block element is smooth, but inwall has a lot of outstanding levels and vertical reinforcement stiffening rib, this allows the main wall of module component to have limited thickness and still provides high rigidity and corrosion simultaneously, thereby has obviously reduced the weight of Prefabricated block element.The vertical side walls that width reduces has the groove that is preferably the trapezoid cross section along whole height, is used to form the cement connecting joint.
Each horizontally disposed reinforcement stiffening rib all have run through its whole length central longitudinal to pipe, be preferably flexibility and the tensioned cables that is formed from steel passes this central longitudinal to pipe.They provide horizontal globality between the Prefabricated block element that constitutes each part of tower, thereby help to increase whole rigidity and stability.This globality will preferably partly realize by each horizontal-extending route is divided into two cables, rather than only have a cable part, thereby by means of relevant jack (jack) or the described cable of similar tool tensioning easily.For this reason, Prefabricated block will have the suitable opening that can enter horizontal central tube.
When the Prefabricated block element of forming each part of tower during the placed side by side each other and horizontally disposed tensioned cables of tensioning, vertical connecting joint between the every pair of module component is with closure, at first by closed Sealing from the outside and inner seal joint, the sealant that will be preferably the cement paste formula subsequently is poured onto in the gap that the side channel by the adjacent block element forms, when cement paste solidifies, will help the globality of unit.
The Prefabricated block element also has a plurality of vertically being arranged in the wall and fully integrated the siphunculus that is formed in the wall, siphunculus be used to make be preferably flexible, provide the tensioning wirerope of vertical globality to pass for the each several part of forming tower.These vertical tensioned cables will be installed from the bottom stiffening rib of the Prefabricated block element that forms the tower lower part, pass the siphunculus of filling with mortar subsequently, thereby mortar is fixed cable and be formed on and fixes in the siphunculus and be formed in the wall, cable not only internally but also from externally hidden, and fully and tower be consolidated.Described cable is installed (being three cables) in groups with cable of each tower section in the example of preferred implementation, make that like this first cable in every group will be in the joint tensioning between first and the second portion; Second cable in every group will be in the joint tensioning between second portion and the third part, or the like.Like this, they help along the whole tower of whole height tensioning.Siphunculus is filled mortar and other similar item subsequently.Like this, vertical cable fully and the tower wall form as one, help the rigidity of tower wall, but make cable keep hidden and can't see from the tower inboard and the outside.
For this reason, as using vertical tensioned cables, the vertical joint of forming the different piece of tower can use jointing method general in the precast concrete product to carry out, and for example the appearance of being filled with the cement paste of white-out rainwater by the groove protection connects or bridle joint.Feature of the present invention is, the vertical assembly of tower will vertical strengthened the angular displacement that stiffening ribs are separated from each other and be assemblied in the top of each other by horizontally rotating two, therefore the vertical non-alignment not of the vertical connector slot between the Prefabricated block element of every part, the perfection that can not change between the vertical stiffening rib is supported, and has improved water resistance.In order to make this rotation become possibility, each Prefabricated block element preferably has two complete vertical stiffening ribs, and has two and half stiffening ribs in the end, forms the stiffening rib of an equivalence when being bonded together.
Being connected to make with the grappling technology by means of the capital construction of using in building, for example tighten according to the suitably definite stiff rod of the size of tower or similarity piece with size routinely of the base portion of tower first and ground carries out.
The decline of tower can be connected to another precast concrete or the metalwork of tower, and perhaps it can directly support shell of wind-driven generator and blade support structure.
The prefabricated modular tower that is proposed has a plurality of advantages than present available system, and wherein most important advantage is to use the element of lesser amt can make up very high tower fast.In the example of preferred implementation, can find out use only 13 Prefabricated block elements how to build the how high tower of 100m, wherein only need three kinds of dissimilar module components, thereby only need three kinds of different mfg. moulding dies.
Another significant advantage is, because the Prefabricated block element is equipped with the reinforcement stiffening rib, so their weight is obviously lighter, this is convenient to transportation and has therefore saved manufacturing, transportation and installation cost.
Emphasize that following unquestionable advantage is important, that is, in the example of preferred implementation, the size of each Prefabricated block element is according to their approximate length calculating, they are between 30 to 35m, and the Breadth Maximum of each element is that 4.5m is so that conventional road transport becomes possibility.Suppose the normally about 70cm of surplus, in transportation, perhaps at the scene in the assembling process, the interim stiffening device of metal lattice work form can be provided with in position to support these parts.
Another advantage of the present invention is whole tower by cable flatly and vertically perfect tensioning.
Must be noted that following significant advantage, vertical cable is formed on Ta Bizhong fully integratedly, pass and be plugged in the wall and the siphunculus of filling with mortar subsequently, this helps their rigidity, but cable keeps hidden and all can not see in the inboard and the outside of tower, this has also improved the durability of cable widely because avoided with the external world contact and bad by the change due to the air.
